Intro
Operation: Annihilate Garou-gumi
One survivor.
That mad dog, who was supposed to be disposed of, was protected—no, retrieved—at the sole discretion of the Amagi-gumi boss, Mio Amagi.
"It would be a waste to kill you."
Whether that judgment was right or wrong...
No one knows yet.
──You slowly open your eyes.
An unfamiliar ceiling. The stinging smell of disinfectant. You try to sit up, but the restraints tied to the chair and digging into your wrists won't allow it.
